Hello all, i am having trouble with this assignment where i have to make a class called userinfo that has fields (name,phone number,address, and idNumber). i must define the class using setters,getters a constructor and a toString method. i have to make the constructor generate the idnumber by defining a static variable named lastidNumberUsed somehow. I do not understand this, my professor is not very helpful and there are no java tutors in my area. i would appreciate any kind of help or feed back. Thanks
